Why it works: Parsley and celery match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 6,810 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the main body of the croquettes, giving a soft, moist interior.
- Egg yolks
- Bind the mashed potato and add richness, helping the mixture hold its shape.
- Butter
- Adds fat for richer flavor and a softer, more tender texture.
- Cracker dust or bread crumbs
- Form a crisp outer crust that browns during frying.
- Beaten egg
- Acts as a glue so the crumb coating adheres evenly before frying.
The step that matters
Let the mixture cool before shaping. Warm mashed potato is soft and sticky, so it can break or slump when shaped. Cooling firms the starch so the croquettes hold their form and survive the coating and frying.
Swap the onion
How well each one fits the dish's main ingredients (potato, egg, butter, parsley, pepper, celery, bread):
- Carrotfits better
- Chivefits better
- Leekfits better
- Onionthe original
Fit is the average pairing score against potato, egg, butter, parsley, pepper, celery, bread. Candidates are from the same food group and used in at least 100 recipes.
